When I try to solve the equation system below, which as far as I understand has an unique solution, the result I get is an empty list, no complaint, no error message, no hint.

What is it I haven't grasped?

Thanks in advance for any tip

(%i27) solve([ri_r=(ri*r)/(ri+r),r0_r=(r0*r)/(r0+r),u=e*(ri_r/(r0+ri_r))+vi*(r0_r/(ri+r0_r))],[r]);

I can tell you what you haven't grasped. This is a car enthusiast forum for the Nissan Maxima....not a math forum. About every 6 months one of you Math dudes pop up on here asking for help with math equations.

And here's a tip. Find a Math forum.
